Mooman RAWKS

From CGWiki

Derived probably from Presidential Jam in which, near the ending, Mooman takes the wig with the bomb thus saving everybody at his own expence, to which the jam is finished with the nostalgic sigh of everyone present: "Mooman truly did rawk!" Even so, this catchphrase could have been used even before presidential jam, which deserves more research. This catchphrase is used whenever Mooman does something awesome and time-consuming, just for amusement of his forum pals. Example: Mr. Bob You rock my world
